==== ### ==== 目標先抓每天補 +1 ppm K(多數草景穩、也不容易引爆藻) * 需要量:1 / 0.215 ≈ 4.7 mL/天 ✅ 建議:K₂SO₄ 設定 4.5–5.0 mL/天(每日) ===== 你 NO3 已經 5–10 ppm,這其實很剛好。 ===== 我建議改成: * 每週測 2 次 NO3(例如:週三、週日) * 規則: - 若 NO3 ≥8 ppm:KNO₃ 停打/或只打 1–2 mL/天保底 - 若 NO3 5–7 ppm:KNO₃ 2–3 mL/天 - 若 NO3 <5 ppm:做一次「校正補」把它拉回 8 ppm - 需要提升 3 ppm → 3 / 0.367 ≈ 8.2 mL(一次補) ✅ 起手式建議(最保守、最不容易爆藻) * 先把 KNO₃ 設定成 1.5–2.0 mL/天 * 然後用上面規則靠 NO3 測值微調 ===== 因為高密度魚+餵食通常 PO4 不會低到哪去;你若盲打,反而是藻的風險。 ===== ✅ 沒試劑時的安全策略(用「症狀」當訊號): * 先停掉 PO4 日加 7–10 天,只觀察: - 若出現綠斑藻(硬點、玻璃/慢草葉面一點一點)、新葉偏慢、矮珍珠卡住:通常代表 PO4 可能偏低 → 才開始「小量補 PO4」 * 小量怎麼補?因為你沒提供 Activate 這瓶的濃度/標示,我不猜 mL: - 用瓶身建議日劑量的 1/4~1/3 作為起手式(每日或隔日) - 一旦綠斑藻減少、長勢恢復,就維持;若開始出現絲藻/褐藻上升,就再往下修 : ===== 你有:TBS 紅色水草液肥、TBS 螯合鐵、Excel。 ===== 但你沒提供瓶身建議劑量/濃度,所以我只能給保守但有效的方向: * 紅色水草液肥:用「瓶身建議量的 1/2」拆成日加(每天小量比一週一次大灌更穩) * 螯合鐵:建議更保守 - 先從「瓶身建議量的 1/3~1/2」日加或隔日加開始 - 如果出現絲藻/黑毛變多,鐵先下修 * Excel(液態碳):你又有 CO2,Excel 更像是「點狀藻/黑毛輔助」用途 - 不建議當成每天主力碳源猛加,容易讓蝦/某些草不舒服 - 需要用時以局部點滴或低量全缸保守用即可
